Photovoltaic panels have been installed on the RSF rooftop that will help offset the energy used in the building.Credit: Dennis Schroeder

Outside air is passively preheated via transpired solar collector (a technology developed by NREL) on the RSF's south facing wall, which is just one of many energy-efficient features of the building.Credit: Pat Corkery

Many materials used in the RSF contain recycled content or come from within 500 miles of the site, including lobby walls made from pine beetle kill wood, counters made from sunflower seeds, and structural steel columns made from reclaimed gas pipes.Credit: Dennis Schroeder
